A useful technique using a traction device and a rotatable sphincterotome for difficult biliary cannulation of an intradiverticular papilla.

ABSTRACT: An intradiverticular papilla can make biliary cannulation challenging during endoscopic retrograde cholangiopancreatography. With an accompanying video, Asano and colleagues describe their technique using a traction device to expose the papilla and a rotatable sphincterotome to align with the bile duct axis, achieving successful biliary cannulation without adverse events.
